Question

The radius of a circular disk is given as 24 cm with a maximum error in measurement of 0.2 cm. What is the maximum possible value for the radius of the disk?

1) 23.8 cm
2) 24.2 cm
3) 23.6 cm
4) 24.4 cm

Answer 1

The maximum possible value for the radius of the circular disk, considering the maximum error of 0.2 cm, is 24.2 cm. This value is obtained by adding the maximum error to the given radius.

Thus, the correct option is 2.

Step-by-step explanation:

The radius of a circular disk is given as 24 cm with a maximum error in measurement of 0.2 cm.

To find the maximum possible value for the radius of the disk, you add the maximum error to the given radius:

1. Maximum possible radius = Given radius + Maximum error
2. Maximum possible radius = 24 cm + 0.2 cm
3. Maximum possible radius = 24.2 cm

Therefore, the maximum possible value for the radius of the disk is 24.2 cm, which corresponds to option 2).
